§ Mr. Rostasked the Secretary of State for the Environment when he will introduce new standards for the insulation of new domestic properties; when the improved standards will take effect; and for how long the proposed revision of standards has now been under consideration.
§ Mr. Geoffrey FinsbergA first consultation with interested parties on this subject took place early last year. In the light of the response received, I have decided to consult further on certain aspects. Subject to the results of this second consultation, I intend to lay an amendment to the building regulations before Parliament as soon as possible.
§ Mr. Rostasked the Secretary of State for the Environment what thickness of insulation will be required by the new regulations for new houses.
§ Mr. Geoffrey FinsbergIn the further round of consultation which will take place shortly I propose to seek views as to whether the amended regulation for roof insulation should specify a U-value of 0.4 or 0.35 W/m2 °C. The requirement for walls proposed in the earlier round of consultation was a U-value of 0.6 W/m2°C.
